A modification of this experiment led to the discovery of the Sagnac effect
A modification of this experiment led to the discovery of the Sagnac effect, and it had the same result as an experiment in which a capacitor was suspended by a wire. The results of this experiment led to the development of the Lorentz–FitzGerald contraction hypothesis. It used a device that separates a beam of light into two. That namesake interferometer floated in mercury. A significant fringe shift was not observed in this experiment, which set out to measure the velocity of the earth relative to the substance that supports the propagation of light. For 10 points, name this doubly-eponymous experiment performed in 1887 that disproved the existence of ether.
